Answers

Answer 1

Index minerals used to determine metamorphic grade - Index minerals are specific minerals that form at specific temperatures and pressures. Therefore the correct option is option E.

The process of determining metamorphic grade with index minerals is known as metamorphic facies. The identification of index minerals is an essential method for determining the metamorphic grade of rocks. Index minerals' presence and abundance can indicate the grade of metamorphism undergone by a rock.

Index minerals are minerals that indicate a particular grade of metamorphism, with each mineral being formed at a distinct range of temperature and pressure.

To identify the grade of metamorphism of a rock, geologists use a system known as metamorphic facies. Metamorphic facies are a group of metamorphic mineral assemblages that share a similar mineralogy and temperature and pressure ranges. Index minerals are used to classify metamorphic facies.

Various minerals are used to represent each metamorphic facies, and these minerals are known as index minerals. Metamorphic grade is determined by the occurrence of index minerals that have formed only at specific temperatures and pressures.

kids. What is the relative fitness of the vV genotype? show your work

Answers

The relative fitness of the vV genotype can be calculated by comparing it to the relative fitness of the WW genotype. Since WW homozygotes produce, on average, 2.2 kids, and wv heterozygotes also produce, on average, 2.2 kids, then the relative fitness of the WW genotype is 1.0.

Since w homozygotes produce, on average, 1.7 kids, then the relative fitness of the vV genotype is (1.7/2.2) = 0.77. This means that the vV genotype has a lower relative fitness than the WW genotype.

This difference in relative fitness between the WW and vV genotypes is due to the fact that w homozygotes are more likely to have the disease, which reduces their reproductive success.

This is an example of natural selection in action, as individuals with the WW genotype have a higher relative fitness than individuals with the vV genotype, and so the WW genotype is more likely to be passed on to future generations.

Question 1 3 pts The style of eruption depends on the plate tectonic setting in which the volcano is situated. Compare the different eruption styles you could observe at a divergent versus a convergent plate boundary. Make sure to address the roles that composition, viscosity, and gas content play in your answer.

Answers

At a divergent plate boundary, the plates are moving away from each other. This type of plate boundary is typically associated with less explosive eruptions.

Eruptions in this type of setting are usually composed of basaltic magma, which is low in silica content and very fluid.

These eruptions produce lava flows and rarely cause ash and pyroclastic flows. Since the viscosity of basaltic magma is low, gas bubbles can escape easily and cause less explosive eruptions.

At a convergent plate boundary, the plates are pushing together. This type of plate boundary is typically associated with explosive eruptions.

Eruptions in this type of setting are usually composed of andesitic or rhyolitic magma, which is high in silica content and more viscous than basaltic magma.

These eruptions produce ash and pyroclastic flows, and can be more explosive due to the higher viscosity of andesitic or rhyolitic magma.

The gas bubbles are more difficult to escape, so pressure builds up and causes more explosive eruptions.

How does climate change affect albedo?

Answers

Earth's albedo decreases as the amount of snow and ice covering the surface decreases as a result of melting caused by rising global temperatures.

What factor that affects climate is albedo?

The ability to reflect sunlight into space is known as albedo. Sunlight is reflected by deserts, clouds, ice and snow, and aerosols (particles in the air). The more solar energy that is reflected, the higher the albedo; the chillier The albedo is also raised as the ice cover expands as the temperature drops. The growing conditions for alpine grasslands on the TP, where temperature is the primary constraining factor, are improved by increased vegetation coverage, which results in a lower surface albedo and more energy absorbed (Bonan et al. 1992, Betts 2000, Barnes and Roy 2008).

A natural greenhouse effect is the cause of the warm global climate on Earth. Earth's surface is heated by the majority of the Sun's light as it passes through the atmosphere. Infrared radiation is released by the warmed oceans and land. Heat-trapping gases in the atmosphere of Earth absorb some of the infrared radiation.

The landslide that occurred on Mount St. Helens just prior to its eruption created a drop in _______ that allowed dissolved gas in magma and groundwater to expand very rapidly and erupt explosively.

Answers

The landslide that occurred on Mount St. Helens just prior to its eruption created a drop in pressure that allowed dissolved gas in magma and groundwater to expand very rapidly and erupt explosively.

The eruption began with a massive landslide, which caused the top of the volcano to collapse and form a huge crater. This landslide also created a sudden drop in pressure in the volcano, which allowed the gas bubbles in the magma and groundwater to expand rapidly and escape explosively.

The release of gas from the magma and groundwater led to a powerful eruption that blew out the north side of the volcano, sending a massive cloud of ash, rocks, and gas into the air. The eruption was also accompanied by a series of pyroclastic flows, which are fast-moving, superheated clouds of ash and gas that can travel long distances from the volcano.

The landslide that preceded the eruption played a critical role in the explosive nature of the eruption. Without the sudden drop in pressure caused by the landslide, the gas bubbles in the magma and groundwater might have slowly and gradually released without creating a catastrophic eruption. Instead, the landslide created a sudden release of gas that led to an explosive eruption, causing widespread destruction and loss of life in the surrounding areas.

which one of the following measurable characteristics in volcanoes is not used to forecast volcanic eruptions question 8 options: a) volcanic earthquakes b) ground deformation c) tectonic earthquakes d) volcanic gas emissions

Answers

The correct answer to this question is option C, tectonic earthquakes. Tectonic earthquakes are caused by the movement of the earth's tectonic plates, which are separate from the movement of magma in volcanoes.

Magma movement in volcanoes can be monitored through volcanic earthquakes, ground deformation, and volcanic gas emissions.

Volcanic earthquakes occur when the magma in a volcano moves, causing a seismic event. Volcanic earthquakes are a major indicator of an impending eruption, as they occur most frequently before an eruption.

Ground deformation occurs when magma accumulates in a volcano and causes the ground around it to bulge. Ground deformation is often used to detect magma accumulation in the magma chamber, which is a major sign of an impending eruption.

Volcanic gas emissions can also be used to predict volcanic eruptions. When a volcano is building up pressure, it will start to release gas, including sulfur dioxide and carbon dioxide, before an eruption. These gas emissions can help to identify an impending eruption.

In conclusion, tectonic earthquakes are not used to forecast volcanic eruptions, as they are not caused by magma movement in volcanoes. Volcanic earthquakes, ground deformation, and volcanic gas emissions are all used to predict an upcoming volcanic eruption.

Frederick Vine and Drummond Matthews:

In the late 1960s, Frederick Vine and Drummond Matthews proposed the magnetic stripe reversals on the seafloor. They discovered that the magnetic stripes on the seafloor alternated in polarity and that the age of the seafloor increased with its distance from the mid-ocean ridge.

This observation showed that the seafloor was spreading from the mid-ocean ridges and validated the theories of seafloor spreading proposed by Hess.

c. When the amount of water exceeds the capacity of the river's channel. The excess water overflows the river's banks and spills out across the flood plain. D. Prolonged rainfall leading to the satiation of the ground

Answers

Flooding occurs when the amount of water exceeds the capacity of the land or the rainfall. The correct option is B.

This can happen due to several reasons, such as heavy rainfall, melting snow, or a high tide. When the capacity of the river’s channel is exceeded, the excess water overflows the river’s banks and spills out across the flood plain. Prolonged rainfall can also lead to flooding, as the water will saturate the ground and begin to pool in low-lying areas.

In addition, flash floods can occur when a heavy rainstorm or thunderstorm happens in a very short period of time, making it difficult for the ground to absorb the water. In any case, when flooding occurs, it can result in significant damage to property, infrastructure, and the environment, making it important to take precautions to prevent flooding where possible.

The factors that describe the metamorphic conditions at a mid-ocean ridge are hot, watery fluids.

What are mid-ocean ridges?

Mid-ocean ridges are linear underwater mountain chains that run along tectonic plate boundaries. They are found where two tectonic plates diverge or move away from each other.

Mid-ocean ridges account for about 20% of the Earth's surface area. They also have a major role in oceanic crust formation.

Metamorphic conditions at a mid-ocean Ridge

The following are the factors that describe the metamorphic conditions at a mid-ocean ridge:

Hot, watery fluids - Hot water with minerals like sodium and calcium is released through hydrothermal vents on mid-ocean ridges. This process is called hydrothermal metamorphism. These fluids react with the minerals in the surrounding rock, resulting in the formation of new minerals and rock textures.

Low pressure - Hydrothermal vents on mid-ocean ridges are under very low pressure due to the high pressure of the surrounding ocean water. The low pressure allows minerals and hot water to circulate freely, resulting in the formation of new minerals and rock textures.

Low temperature - Hydrothermal fluids in mid-ocean ridges have a lower temperature than those in continental settings. However, they are still hot enough to cause metamorphism in the surrounding rock.

identify the conditions that are likely to help preserve animal remains, making it more likely for them to become fossils.

Answers

Answer:

The following conditions are likely to help preserve animal remains, making it more likely for them to become fossils:

Rapid burial: When an animal dies, it is important that its body is quickly buried by sediment or other materials, which can protect it from scavengers, decay, and weathering.

Low oxygen environments: In low oxygen environments, such as swamps, bogs, or deep ocean sediments, decomposition slows down, which can help preserve the animal's remains.

Hard parts: Animals with hard parts, such as bones, teeth, or shells, are more likely to be preserved as fossils than those with soft tissue because hard parts are more resistant to decay and can survive burial and fossilization processes.

Lack of disturbance: If an animal's remains are not disturbed or moved after burial, they are more likely to remain intact and undergo fossilization.

Mineral-rich water: When mineral-rich water percolates through buried remains, it can replace the organic material with minerals, preserving the structure of the original organism and creating a fossil.

It is important to note that the likelihood of an animal becoming a fossil depends on a combination of factors, and even under ideal conditions, fossilization is still a rare event.

the distinctive vertical joints seen in this basalt flow most likely formed as a consequence of which of the following?

Answers

The distinctive vertical joints seen in this basalt flow most likely formed as a consequence of thermal contraction. Thermal contraction occurs when hot molten rock cools and contracts upon cooling. As the rock cools, fractures form which create the vertical joints seen in the basalt flow.

Thermal contraction is common in basalt flows and can result in a variety of joint types, depending on the rate of cooling. As the molten rock cools, it contracts and fractures, resulting in a network of vertical and horizontal fractures, which can range in size from millimeters to centimeters. As the rock cools further, these fractures can become more pronounced, resulting in distinct vertical columns of rock.

The rate of cooling of the molten rock is a major factor in determining the size and pattern of the vertical joints in the basalt flow. If the molten rock cools quickly, it contracts more rapidly and thus more fractures form, creating a more pronounced pattern of vertical joints.

Conversely, if the molten rock cools slowly, the contraction is slower and less fractures form, resulting in a less pronounced pattern of vertical joints.

The cooling of the molten rock is also affected by the type of environment it is exposed to. Basalt flows in a temperate environment will cool at a slower rate than those exposed to a colder environment, thus producing a different pattern of vertical joints.

In conclusion, the distinctive vertical joints seen in this basalt flow most likely formed as a consequence of thermal contraction. The size and pattern of the joints is affected by the rate of cooling of the molten rock, as well as the type of environment it is exposed to.

Base your answers to questions 1 through 4 on the passage and cross section below and on your knowledge of Earth science. The cross section represents a generalized region of the Pacific Ocean along the equator during normal (non-El Niño) conditions. The relative temperatures of the ocean water and the prevailing wind direction are indicated.
El Niño Under normal Pacific Ocean conditions, strong winds blow from east to west along the equator. Surface ocean water piles up on the western part of the Pacific due to these winds. This allows deeper, colder ocean water on the eastern rim of the Pacific to be pulled up (upwelling) to replace the warmer surface water that was pushed westward. During an El Niño event, these westward-blowing winds get weaker. As a result, warmer water does not get pushed westward as much, and colder water in the east is not pulled toward the surface. This creates warmer surface ocean water temperatures in the east, allowing the thunderstorms that normally occur at the equator in the western Pacific to move eastward. A strong El Niño is often associated with wet winters along the northwestern coast of South America and in the southeastern United States, and drier weather patterns in Southeast Asia (Indonesia) and Australia. The northeastern United States usually has warmer and drier winters in an El Niño year.

Answers

The rock cycle is the process through which rocks are continually changed from one form to another.

This cycle is driven by the action of Earth's tectonic and surface processes, such as erosion and weathering.

Rocks are constantly being recycled through the rock cycle, moving from one form to another and then back again.

The three main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form when magma cools and crystallizes. Sedimentary rocks are formed from the weathering and erosion of existing rocks.

Metamorphic rocks are formed when heat and pressure cause existing rocks to change form. All three of these types of rocks can be found in the rock cycle, and they are all interrelated.


The rock cycle is not a linear process. Instead, rocks may move back and forth between different stages of the cycle, or they may undergo multiple changes before being reabsorbed into the environment.

The most common cycle starts with igneous rocks, which are then broken down into sedimentary rocks through erosion and weathering.

Metamorphic rocks are then formed when the sedimentary rocks are exposed to intense heat and pressure. Finally, the metamorphic rocks may be melted down and reabsorbed into the environment.

The rock cycle is an important process for shaping the surface of the Earth, and it is a key part of the Earth's geologic system.

Without the rock cycle, rocks would not be able to be recycled and reused in different forms, and the surface of the Earth would look very different.
